Characterization of dimension, hydrogen capture and catalytic hydrogenation features of Pd nanoparticles. HR-TEM images of PdH (A) and Pd nanoparticles (B) (insert images are the corresponding selected area electron diffraction patterns), their hydrated diameter distributions (C), simulated local hydrogen capture illustration (D) and corresponding UV absorption evolution (E) for monitoring dynamic process (F), and simulated catalytic hydrogenation illustration (G) and corresponding UV absorption evolution (H) for monitoring dynamic process (I).
